I started to bleed last night after sex. I went to the ER and they did a vaginal ultrasound. Saying my sack is sizing at 6weeks but there is no fetal pole.  So he said that either it did not produce the embryo or I'm not far enough along. My hormone levels have went up from 12,400 to 13,488.  He said they should have doubled since last tested on Thursday night. He said that it's still rising but not as fast as it should. Also no embryo is in the sack. Maybe that I'm just not as far as the y think???
